The aim of this study was to determine the impact of increased copper contents on selected physiological processes in oneyear-old Pinus sylvestris L. needles from a former German timber storage area in Warcino Forest District, a subject to an environmental quality survey. Samples were collected from the area with the high copper content in the soil. The control area was a nearby pine tree stand showing...
Clove oil and its principal constituent, eugenol, display herbicidal contact action on annual broadleaf weeds. In the present study, we examined the early effects of clove oil (CL) and its main constituents: eugenol (E), eugenol+humulene (E+H) and eugenol+caryophyllene (E+C) on the physiological state of broccoli leaves during the first 60min after application. We also addressed the hypothesis that...
